Question

Which cell(s) must use ATP energy to move the molecules out of the cell? (Hint: When using energy by the cell molecules will move from Low to High)

im not sure if its, both of them or a or b

Answer 1

Answer:

Cell A

Explanation:

The process in cells that requires energy to transport the molecules from low concentration to high concentration is called active transport. During active transport, molecules move against the concentration gradient, from low to high concentration.

In the given diagram, cell A uses ATP energy to move the molecules out of the cell because the molecule concentration is high outside the side and molecules are moving from inside to outside that is from low to high concentration.

Hence, the correct answer is "Cell A"
